New research has revealed that agriculture came to Europe amid a wave of immigration from the Middle East during the Neolithic period. The newcomers won out over the locals because of their sophisticated culture, mastery of agriculture -- and their miracle food, milk.

Wedged in between dump trucks and excavators, archeologist Birgit Srock is drawing the outline of a 7,200-year-old posthole. A concrete mixing plant is visible on the horizon. She is here because, during the construction of a high-speed rail line between the German cities of Nuremberg and Berlin, workers happened upon a large Neolithic settlement in the Upper Franconia region of northern Bavaria.

The remains of more than 40 houses were unearthed, as well as skeletons, a spinning wheel, bulbous clay vessels, cows' teeth and broken sieves for cheese production -- a typical settlement of the so-called Linear Pottery culture (named after the patterns on their pottery).

The new settlers also had something of a miracle food at their disposal. They produced fresh milk, which, as a result of a genetic mutation, they were soon able to drink in large quantities. The result was that the population of farmers grew and grew.

These striking insights come from biologists and chemists. In a barrage of articles in professional journals like Nature and BMC Evolutionary Biology, they have turned many of the prevailing views upside down over the course of the last three years.

The most important group is working on the "Leche" project (the name is inspired by the Spanish word for milk), an association of 13 research institutes in seven European Union countries. The goal of the project is to genetically probe the beginnings of butter, milk and cheese.

An unusual circumstance has made this research possible in the first place. Homo sapiens was originally unable to digest raw milk. Generally, the human body only produces an enzyme that can break down lactose in the small intestine during the first few years of life. Indeed, most adults in Asia and Africa react to cow's milk with nausea, flatulence and diarrhea.

But the situation is different in Europe, where many people carry a minute modification of chromosome 2 that enables them to digest lactose throughout their life without experiencing intestinal problems. The percentage of people with this modification is the highest among Britons and Scandinavians.

It has long been known that these differences are based on Europeans' primeval origins. But where did the first milk drinker live? Which early man was the first to feast on cow's milk without suffering the consequences?

Revelation 13

And I stood upon the sand of the sea, and saw a beast rise up out of the sea, having seven heads and ten horns, and upon his horns ten crowns, and upon his heads the name of blasphemy...

...And they worshipped the dragon which gave power unto the beast: and they worshipped the beast, saying, Who is like unto the beast? who is able to make war with him?...

Mark 13

And when ye shall hear of wars and rumours of wars, be ye not troubled: for such things must needs be; but the end shall not be yet. For nation shall rise against nation, and kingdom against kingdom: and there shall be earthquakes in divers places, and there shall be famines and troubles: these are the beginnings of sorrows.
